Abstract
An apparatus providing effective control of fluid temperature to achieve temperature control precision of ±0.1° F. at flow rates exceeding five gallons/minute includes a hot and a cold reservoir of process fluid maintained at their desired temperatures by a high-accuracy industrial chiller and an industrial heater, respectively. A control valve mixes fluid from the reservoirs to produce a precisely controlled stream of process fluid delivered to the point of usage. Another flow control valve maintains system flow at a precise value.
